Title: Digital inductive anti-theft system
Inventor: CHOW CHO-KI
IPC: B60R25/00
Filed: 2004-04-16
Abstract: The digital inductive anti-theft system uses the visual inductive function of crystal chips to immobilize a car's starter system, making a vehicle unstartable without the verification unit, which is encoded with personalized identification data of three or more users. Once the code is verified and recognized, the magnetic fuel cut-off device is released and the car can be started as usual. If the verification process lasts more than three seconds, the alarm will be activated and the fuel cut-off device continues to suspend fuel supply, making the vehicle unstartable. This system can fit on any vehicle, domestic or import.

Title: Interoperable credential gathering and access modularity
Inventor: STEPHENS JOHN
IPC: G09C1/00
Filed: 2004-09-16
Abstract: A credential is translated with one of different credential provider modules each translating a corresponding different type of credential into a common protocol. The translated credential is communicated through an API to a logon UI module to an operating system (OS) of a local machine. An OS logon module is called by the logon UI  module to authenticate the translated credential against a credential database. A user identified by the translated credential is logged on to access the local machine when the authentication is successful. The credential can also be used with a selection received from the logon UI module via a corresponding one of different pre-log access provider (PLAP) modules that each communicate with the API. The API establishes a network session with an access service specified by the selected PLAP module when the credential is authenticated with the credential database.

Abstract: The invention relates to a testing device and to a method for verifying the charge invoicing for a communications device according to time unit intervals.  According to the invention, a testing device, which can simulate at least one calling analog terminal and at least one called terminal, is connected to a network node that generates time pulses. At least one predetermined test communications connection is set up and terminated over at least the one network node (40). In addition, the time interval between the beginning of the test communications connection and the generation of a first time pulse is determined and verified to ascertain whether the determined time interval is located within a first predetermined time domain. During the existing test communications connection, time unit intervals of successive time pulses are measured and compared with a predetermined time interval. It is also verified as to whether at least one additional time pulse was received after the termination of the test communications connection. If this is the case, then the time interval between the termination of the test communications connection and the at least one time pulse is determined and verified to ascertain whether the determined time interval is located within a second predetermined time domain.

Title: Clamping apparatus with a chuck and a pallet releasably attachable thereto
Inventor: NIE PETER
IPC: B23Q1/00
Filed: 2005-03-17
Abstract: The clamping apparatus comprises a chuck member and a pallet releasably attachable thereto. The chuck member has four centering grooves, arranged offset to each other by 90° around the central Z-axis, while the pallet has four correspondingly located centering pins. In each of the four centering grooves, one of the groove flanks serves for centering the associated centering pin of the pallet, while the other groove flank is constituted by a clamping member. Upon clamping the pallet to the chuck member, the associated clamping member engages a recess provided on the centering pin and pulls the latter one in Z-direction into the centering groove of the chuck member. Simultaneously, the clamping member also presses the centering pin against the other groove flank. Thereby, the pallet is positioned relative to the chuck member in X-, Y- and Z- directions and clamped to the chuck member.
